Description: Open the attached file and save it as PPTX. Open the resulting file in PowerPoint. PowerPoint fails to open the file. Both officeotron and OOXML validator doesn't give any errors. If we initially save the file in PowerPoint and roundtrip it in LO, it opens without any problem in PowerPoint. The issue seems to be with additional export of audio in animations. If we unzip the pptx file saved in LO and look at the formatted slide1.xml, in animations we have the below xml ``` <p:audio isNarration="0"> <p:cMediaNode showWhenStopped="1"> <p:cTn/> <p:tgtEl> <p:sndTgt r:embed="rId1" name="wind.wav"/> </p:tgtEl> </p:cMediaNode> </p:audio> ``` This audio element is not attached to any valid node. If we remove this part from the XML and rezip it, the resulting file opens without any problem in PowerPoint Steps to Reproduce: 1.Save the attached in as PPTX 2.Open the resulting file in PowerPoint 3.PowerPoint fails to open the file Actual Results: PowerPoint opens the file without any issues Expected Results: PowerPoint fails to open the file Reproducible: Always User Profile Reset: Yes Additional Info: Version: 25.2.3.2 (X86_64) / LibreOffice Community Build ID: 520(Build:2) CPU threads: 22; OS: Linux 6.12; UI render: default; VCL: gtk3 Locale: en-IN (en_IN); UI: en-US Debian package version: 4:25.2.3-2+deb13u2 Calc: threaded

Oh, I mixed up the bug report reference in my commits, those were for bug 169706, a somewhat similar, but different issue.
